Scenario
You are a software developer for a retail company that sells mobile phones via the web. Your company has deployed the entire website onto the public cloud. The mobile manufacturing company launches a new mobile every year. Your company’s website gets ten times the traffic during the new mobile launch. Customers often complain about the timeout and slow website performance. Some of them are even moving to other competitor’s websites, directly impacting your annual profit.

The public cloud provides various options to handle website scalability. Your manager has asked you to investigate various alternatives and walk through the best possible cost-effective solution. The goal is to handle the scale-up of the application during the pick load and scale down during the less load.
